【 摘 要 】

This work is concerned with the adhesion strength between a paper web and a metal roll surface which is a common situation in paper machines world-wide It is shown that the classic expression relating the work of adhesion to the peeling angle and web tension is in general insufficient An improved model is suggested to take into account the energy dissipation due to elastic-plastic deformation behavior of wet paper materials To judge the model an industrially relevant example of wet newsprint and a mild steel surface is studied It is found that the agreement between theory and experimental observations is excellent A key result is that elastic-plastic material behavior must always be Included for wet paper materials in peeling processes (C) 2010 Elsevier Ltd All rights reserved
